Radosavovic et al. [1]} investigate the network design spaces of model selection and design approaches. They propose to compare design spaces by contrasting the estimated distributions of model complexity in the network design spaces. Using their proposed method of comparing the distributions of model complexity of network design space, they investigate several popular NAS approaches, such as ENAS [2]} and DARTS [3]}, and find that there are significant differences between the network design spaces of these approaches.
